Question

find the slope if it exists
x = -5

Answer 1

It does not exist

Answer 2

so it is undefined

Answer 3

It does not exist

Answer 4

what do you mean

Answer 5

it is a straight line so the slope does not exist

Answer 6

so that means the slope is undefined I have two choices to choose from
a. the slope is --?
b. the slope is undefined

Answer 7

b

Answer 8

The slope is zero for a horizontal line and undefined for a vertical line such as y = -5.

Answer 9

thanks i choose undefined

Answer 10

It should be zero though jazi1.

Answer 11

so in other words the slope is 0

Answer 12

Yes.

Answer 13

thank you I had so many answers on this last night some say undefined and some say dont make sense

Answer 14

To better understand this, the slope is the change in y over the change in x. (y/x)

If you have a horizontal line, such as your problem x = -5, there is no change in y, so you have (0/-5) which is equal to zero.

On the other hand, if you had a vertical line such as y = -5, there is no change in y, so you have (-5/0) and that is undefined. (You can't divide -5 by 0).

Answer 15

SORRY. Correction with my last statement. It should say "...a vertical line such as y = -5, there is no change in X..." not y.

"On the other hand, if you had a vertical line such as y = -5, there is no change in x, so you have (-5/0) and that is undefined. (You can't divide -5 by 0)."

Answer 16

Answer 17

0 is the correct answer.

Answer 18

okay we got somewhere thansk dearly

Answer 19

Sorry to correct you bobby but 'undefined' is the right answer. You previously gave incorrect answer to tena32 as well regarding a similar question.

Answer 20

You're right, I'm mixing up my axes.

Answer 21

you must inform Tena32 as well, so that tena32 does not mix his/her axes
